:The Red Book is wrong. The SC chip has 12.2 billion xtors.

According to IBM redpapers, the SC chip has 9.7 billion transistors but the wiki entry shows 12.2 billion? — Preceding unsigned comment added by 99.82.166.5 (talk • contribs)
- The Red Book is wrong. The SC chip has 12.2 billion xtors. Anyway 9.7 wouldn't even make sense (I think they originally mistakenly said 9.2B) because the z14 is 9.2B and they added 288 MiB of eDRAM which just the bitcells alone is 2.5B xtors + 2.5 caps, not including the rest of the logic. --David (talk) 11:41, 9 May 2020 (EDT)
